Hi Aleksandar, thanks for breaking down the new features so clearly. The smooth switching between local and cloud stood out to me the most
GitHub review integration sounds neat, but curious how well it handle large monorepo cases? IMO that’s the real test.
Congrats on the launch and wishing you big success ahead!
